Pokemon TCG Pocket A4b Leak: High Class Pack EX, Release Date, and What It Means for Players

The next miniset for Pokemon TCG Pocket may have leaked, giving fans an early look at its title, release date, and unique approach to card distribution. If true, the upcoming A4b set will not only mark the possible end of the A-series but also introduce a new way for players to complete their collections.

A4b Could Be the Final A-Series Expansion

Leaks surrounding Pokemon TCG Pocket are nothing new, but what makes this one interesting is its source. The official Japanese Pokemon TCG Pocket account reportedly posted the teaser trailer for A4b earlier than intended. Although the tweet was quickly deleted, fans managed to grab details before it disappeared.

According to the leak, the set is scheduled to release on September 30, 2025, and is titled “High Class Pack EX” (translated from Japanese, so the English title may differ). Unlike past expansions, this set is rumored to contain no new cards. Instead, it will re-release A-series cards, some featuring updated illustrations. This suggests that A4b is designed to help players catch up on missed cards before the B-series begins.

Smaller Booster Packs With Guaranteed EX Cards

Another standout detail is the way booster packs will work in this miniset. Instead of the standard five or six cards, each A4b booster will reportedly contain four cards. However, one of those cards is guaranteed to be an EX or four-diamond rarity card, which fits the “High Class Pack EX” theme.

This is a surprising change since DeNA recently moved from five-card packs to six-card packs — and is now experimenting with a different format altogether. While unusual, the guaranteed rare card may make these smaller boosters more appealing to collectors.

What This Means for Competitive Play

The A4b leak has reignited debates about the future of competitive play in Pokemon TCG Pocket. Some fans believe this confirms that A-series cards will eventually be rotated out once the B-series era starts. By re-releasing older cards now, DeNA could be giving players one last opportunity to complete their Pokedex collections before those cards are removed from PvP ranked play.

Others argue it’s too soon for a rotation. In the physical Pokemon TCG, card sets usually stay legal for several years before being retired. Whether or not DeNA follows this tradition remains to be seen, but A4b appears to be a transitional expansion — one that closes out the A-series and prepares the game for its next phase.

Pokemon TCG Pocket A4b Release Date

The leaked trailer revealed that Pokemon TCG Pocket A4b: High Class Pack EX is set to release on September 30, 2025. If confirmed, fans won’t have to wait long to see whether the rumors about smaller packs and guaranteed EX cards are true.

If the leaks are accurate, Pokemon TCG Pocket A4b is shaping up to be a unique miniset. With no new cards, guaranteed EX pulls, and a possible farewell to the A-series, it could mark an important turning point for the mobile card game.

Whether you’re a collector trying to finish your Pokedex or a competitive player watching for rotation news, A4b may be the expansion that sets the stage for Pokemon TCG Pocket’s next era.
